PIC16C54A PIC16C54C Migration
This document intended describe functional differences electrical specification differences that present when migrating from device next. Note: Even though compatible devices specified tested same electrical specification, characteristics devices different from each other (due process difference). systems that were designed device specifications, these process differences should cause issues application. systems that tightly meet electrical specifications, process differences cause device behave differently application.
Table shows considerations that must taken into account when migrating from PIC16C54A PIC16C54C.
